We define the Kondo temperature \(T_K^{(\tau )}\)  as the temperature for which the contribution of
channel \(\tau \)  to the zero-bias conductance for \(D=B=0\)  falls to half of its zero-temperature value [1]}.
For the Kondo model with channel symmetry
[\(J_{-1}=J_1\)  in Eq. (REF )], the
topological transition takes place for \(D_c \sim 2.5 T_K^{(1)}\)  [1]}, but \(D_c\) 
decreases with decreasing \(J_{-1}/J_1\)  ratio. In fact, for \(J_{-1}=0\)  it is
known to be zero [3]}.
In FePc experimentally \(D =5\)  meV [4]} and \(T_K^{(1)} \sim 20\)  meV [5]}.
In Fig. REF  we represent the ratios \(D_c/T_K^{(1)}\)  and \(T_K^{(-1)}/T_K^{(1)}\) 
for intermediate values of \(J_{-1}/J_1\) .
The higher Kondo temperature \(T_K^{(1)}\)  changes only moderately
as \(J_{-1}/J_1\)  varies, from 0.024 for \(J_{-1}/J_1=0.2\)  to 0.018 for \(J_{-1}/J_1=0.7\) 
as a consequence of the competition between both channels [6]}.
Instead, \(D_c\)  and particularly \(T_K^{(-1)}\)  have a strong dependence on \(J_{-1}\) 
in the range considered.
